What sort of details are you looking for? The redirection of the audio stream 
to the network is done within the audio service using software that is specific 
to desktop and application remoting and can't be repurposed outside of those 

Windows XP used the NT4 audio driver model (a.k.a. winmm driver model, MME 
driver model, etc.).

Assuming you are referring to Windows Vista, Windows Server 2008, and later, 
the post-mix audio stream is directed to the network from within the audio 
service. The audio stream does not go to a kernel mode audio driver.

Are the details of this redirection available somewhere?
What about in older systems such as WinXP?
